PRECAUTIONS
• Never touch moving parts.
• Never disassemble while the batteries are installed.
• Always let parts cool before touching.
GEARING
Your vehicle has been equipped with the optimal gearing for the stock platform. It offers an
ideal balance between speed, power and efficiency. Should you decide to customize your
vehicle with optional batteries or motors, it may be necessary for you to change the pinion or
spur gear.
Installing a pinion gear with fewer teeth or a spur gear with more teeth will provide greater
torque but will reduce top speed. Likewise, a pinion gear with more teeth or a spur gear with
fewer teeth will reduce torque and increase top speed. Care should be taken when installing
larger pinion gears as this can “overgear” the vehicle, resulting in overheating of the motor
and ESC. When testing different gearing options, pay close attention to the temperature of
the motor and speed control to ensure you are operating within the temperature range of the
components. The motor or ESC should never be so hot that it cannot be touched. If tempera-
tures are too hot, a different gearing combination with a lower pinion gear and/or higher spur
gear is suggested.
CHANGING THE PINION GEAR/GEAR RATIO
1. Loosen the set screw and remove the installed pinion gear.
2. Loosen the motor screws and slide the motor back.
3. Place the new pinion on the end of the motor shaft so the set screw is located
over the flat on the shaft.
4. Position it so the teeth line up with the spur gear and secure the pinion by tightening
the set screw.
5. Set the gear mesh.

SETTING THE GEAR MESH
The gear mesh has already been set at the factory. Setting it is only necessary when changing
motors or gears.
Proper gear mesh (how gear teeth meet) is important to the performance of the vehicle. When
the gear mesh is too loose, the spur gear could be damaged by the pinion gear of the motor. If
the mesh is too tight, speed could be limited and the motor and ESC will overheat.
1. Loosen the motor screws and slide the motor back.
2. Put a small piece of paper between the pinion and spur gears.
3. Push the gears together while tightening the motor screws.
4. Remove the paper. Check the mesh at 3–5 different locations around
the spur gear for a small amount of movement.
NOTICE:
For a 2S Li-Po battery, use the included 16T Pinion gear. For a 3S Li-Po battery,
use the optional 14T pinion gear (LOSA3574).
NOTICE:
If you use the 16T pinion gear with a 3S Li-Po battery, damage to the vehicle, ESC,
and/or motor will occur.
